Contractor shall include with
each shipment a legible copy of the Material Test Report. The report shall include
the following information:
Name and address
of the manufacturer.
Part number and
the ordering and procurement specification, including revision levels that
controlled the manufacture of the goods.
production order/lot number.
A copy of the Raw
Material Certificate from the original manufacturer.
Raw material data:
Alloy class, type,

Name of raw
report as defined by the applicable specification (i.e., tensile and/or
single/double shear strength, fatigue testing).
examination report as defined by the applicable specification (e.g.,
microstructure and/or macrostructure).
NDT test results: dye penetrate or magnetic particle results, when required by
If Contractor is not the
manufacturer, Contractor's name and JPL's Contract/Purchase Order number will
be referenced on the manufacturer's certificate. Any other distributors, which
have had control of the parts, must be included
Contractor’s Quality Assurance
department shall be responsible for ensuring that items per this Contract/Purchase
Order are packaged in such a manner that the dimensional integrity is
preserved, contamination and corrosion are prevented, and physical damage to
the threads is avoided during shipment. The preferred method, when size permits
(usually #10 and MJ5 and larger), will be to individually sleeve the threaded
portion of the fastener. Any method used shall ensure that threads remain
undamaged during shipment.
Fasteners made of plain carbon
or low alloy steel shall be protected from corrosion. When plating is
specified, it shall be compatible with the space environment (as appropriate). On
steels harder than RC 33 plating shall be applied by a process that is not embrittling to the steel.
For flight applications, Flight
Fastener Materials must have high resistance to Stress Corrosion Cracking
(SCC). The allowed materials are A286, MP35N, Inconel
718, or TI-6Al-4V. For structural fasteners, the minimum required tensile
strength is 160 ksi (1100 MPa).
The preferred plating material is silver. Cadmium and zinc plating is
